Overview


SI-420 Serial to Analog Converter

The Eagle Microsystems SI-420 converts serial data to an analog output allowing data transfer from serial devices to PLC’s and other common analog devices. The device can function in either an passive loop powered or active configuration. The serial input is electrically isolated from the 4-20 mA loop, eliminating any possible ground loop issues between the remote serial device and the current loop.

Convert a Serial Data Stream to An Isolated 4-20 mA Signal

The SI-420 is a 35mm DIN mounted device that converts a number received over an RS232 or 20mA current-loop interface into a proportional 4-20mA output. The device will work in either a passive 24V loop-powered or active 9V to 28V powered configuration. The serial input is electrically isolated from the 4-20mA loop, thereby eliminating any possible ground-loop issues between the remote serial device and the current loop. This product is a great choice to use in low power environments such as hazardous areas or touch safe enclosures. It is also a great choice for retrofitting existing system as the loop powered setting offers an alternative to an independently powered device requiring additional wiring.
